Subject: [PATCH] fix: rewrite markdown doc requests internally instead of 303
 redirect

Agents requesting docs with Accept: text/markdown were getting 303
redirects to .md URLs, which many HTTP clients don't follow properly.
Instead of redirecting, internally rewrite the request to the .md route
and serve the markdown content directly.
